Who says cashback couldn't be exciting? You could get all your money back by using this site

It promises an incredible offer - every 25th customer gets their money back.

Boom25 claims every purchase that shoppers make has the opportunity to be refunded - in full.

The site is partnered with some of the biggest names on the High Street from M&S to Boots and every 25th shopper is a winner.

Boom25 says it pays out in full with just a couple of exceptions: fast food purchases are paid at 50% of the cost and a single food bill cannot be more than £60.

And all car purchases will be paid at 50%. Plus, unlike other purchases, every 59th purchase of a car via Boom25 will be a winner.

The company also charges a handling fee of up to 17%.

Thousands of web users have already signed up - and some say they have already received their cashback.

One user wrote on the Money Saving Expert website: "I joined with Boom25... It has over 600 retailers to purchase from - admittedly there are a lot I have never heard of and am unlikely to use but there are some big websites such as Argos, George at Asda, New Look, Boots, Very and Just Eat. 

"I found it a thrill that instead of earning somewhere between 1-5% of my online spend, I could win my entire amount whether it be £5 or £600.

"Well I started to use Boom25 for my Just Eat initially as I would only usually earn under £1 cashback from Quidco. Unfortunately, I am yet to win from my Just Eat purchases BUT I have now won by money back 5 times from Very, Wilkos and The Entertainer and have received just short of £300 back."
